Coinkite ships the first batch of Opendime — the world's first Bitcoin bearer bond. A small USB stick that holds Bitcoin like a physical coin, Opendime can be passed from hand to hand without touching the blockchain until it's finally "unsealed" to spend.
Demonstrated as a "cyberpunk credstick" at launch, Opendime brought physical Bitcoin transactions to life. Each unit generates a private key internally that even the owner can't see until the device is physically broken open, making trustless in-person Bitcoin transfers possible for the first time.
Disclosure: Coinkite Inc. is the maker of this product and the publisher of this site.
